After crushing, the raw materials are transported to the plant by conveyor. Before homogenized, the plant stores the material. Too finely ground, the materials are transferred to the raw mill, to produce raw mix. The raw mix is preheated before it goes into the kiln, and by the flame, it can be heated to 2000 °c to produce clinker.

February 23, 2024. The raw mill is a grinding machine used to pulverize materials into fine powder. It is a crucial component of cement plants, as it is employed to grind raw …

The cement clinker manufacturing process can be divided into mill-on and mill-off modes according to the raw mill operating conditions (Li et al., 2019, Zheng et al., 2012). When the raw mill is running during the mill-on mode, the flue gas from the precalciner passes through the raw mill into the dust collector before being emitted.

In this study, the problem related to the under-capacity performance of coal mill at Portland cement plant from Negeri Sembilan Cement Industries Sdn. Bhd. (NSCI) company in Perlis will be addressed.
